Hyundai Santa Fe convenience system failure with door locks and automatic back door opening issue on Hyundai Santa Fe

Some Hyundai Santa Fe owners report experiencing issues with door locks and the automatic back door opening system. These problems may include the key fob locking all doors except for one specific door, accompanied by flashing lights. In cases of malfunction with the rear door lock system, owners are advised to seek assistance from an authorized service center or platforms like JustAnswer for proper diagnosis and repair. Additionally, there are common malfunctions and year-specific issues documented in guides that detail recalls and solutions related to door locks. Notably, Hyundai has issued a recall for certain Santa Fe models due to faulty door locks, which can create challenges for owners, such as extended wait times for replacement parts. A frequent cause of these door lock issues is a faulty door lock actuator, which includes a motor, gears, and a rod that controls the locking mechanism. It is recommended that owners consult a professional for diagnosis and repair to ensure the safety and functionality of their vehicle.
